I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller.I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC.The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. This...
hi,I'm new in ST. I'm trying to implement SPI communication between FPGA and STM32L051R8T6 (slave).I've initialized the spi bus in main (HAL_SPI_Init()), so that it is set to use (HAL_SPI_RxCpltCallback).and from main i called HAL_SPI_Receive_IT (to...
Posted on August 16, 2012 at 21:45I came across the following problem: I have a free-running timer, and a signal being input on its TIMx_CH1 pin. I want to capture timer value for two consecutive edges on that signal, so I set up the CC1 unit for ca...
I have configured LED and it blinks properly until timer interrupt occurs. While timer interrupt part is getting executed, LED stops toggling. Once the interrupt part is executed, it starts blinking again. I know this question maybe dumb to many but ...
Hi Team,I want configure STM32G071CBT6 as SPI slave device. Is there any existing linux kernel driver for STM32G071CBT6?Thanks,Arun
Hello,I use internal ADC of the STM32F767 microprocessor. When I plot the converted data in the Excel, I see a step signals initially. But when I check the analog signal input of the ADC with oscilloscope, there is no signal as step signals initially...
I have a capacitor connected and need an example of HAL function that read register which signal that VBAT pin if low level of voltage detected.Thank you.
Want to use SWD pins as GPIO pins.
Hi,I'm receiving characters in polling mode on USART2 in an STM32L476VG.The USART is set up and enabled. I have set the timeout period using LL_USART_SetRxTimeout(USART2, 30000);ie 3 seconds at 9600 baud.My Get Char routine is as follows:int8_t AquaG...
I have a board using an STM32F407VGT6 that draws excessive current from the backup battery for the RTC when board power is bleeding down. The board is powered by 24VDC and bucked to +5V with an LDO used to generate the +3.3V power for the STM32. A ...
